I thought dissociation was part of the symptoms of PTSD. Given the history of being abused as told in the article, I am bit perplexed why doctors decide it was DID.
It is often difficult to get a diagnosis of PTSD when you've not been at war or subjected to a singular catastrophic event. And even if you did, there may not exist treatment pathways for those with PTSD from more complex or long lasting situations :(
It's all on a spectrum with DID being a more "serious/complex" form of PTSD. A DID patient experiences PTSD symptoms, but also symptoms you won't find in PTSD patients.
